UNITED STATES ISAAC HERRMANN, OF ELYRIA, OHIO.

WATCH'MANS TIME-RECORDING MECHANISM.

Application filed June 28, 1923.

To all whom it may concern:

Be it known that I, Isaac HERRMANN, a citizen of the United States,residing at Elyria, in the county of Lorain and State of Ohio, haveinvented a certain new and useful Improvement in Viatchmens Time-Recording Mechanism, of which the following is a full, cle r, and exactdescription, reference being had to the accompanying drawings.

This invention relates to time recording mechanism, and moreparticularly to mechanism of the clock type used by night watchmen andpatrolmen for the purpose of enabling them to make an accurate record ofthe times at which they arrive at a certain place or places on theirrounds or posts, but which will ordinarily prevent any unauthorizedperson from opening the casing for any purpose, as well as preventingany person from opening the casing without leaving a record of suchaction. The invention disclosed herein is an improvement upon arecording clock of this general character shown, described and claimedin my Patent No. 1,231,350 issued June 26, 1917'.

Among the objects of my invention are: to improve and simplify theconstruction and operation of the day-selector disk by means of whichthe recording disk (or other record-receiving element) may be marked byan instrument inserted through the proper aperture in the covercorresponding to the appropriate day of the week (or month) to providenovel arrangement of shutter for the apertures in the cover for therecord-making instrument or device, for the operating arm for theday-selector disk through which the record-marking device is inserted,and for the cover-unlocking mech anism; to provide such shutter with anovel locking means; also to provide a novel construction and mountingfor the instrument or device which is employed with the aforesaidapertures. Further and more limited objects of the invention relate tothe construction and arrangement of parts whereby a simple, economicaland reliable device of this character is produced, all of which will beset forth in the specification in connection with the detaileddescription.

In the drawings Fig. lrepresents a plan view, and Fig. 2 a sideelevation, of the complete device or clock, with the cover and shutterclosed; Figs. 3 and t are front elevations of the device showing,respectively,

Serial No. 648,189.

the shutter opened and closed; Fig. 5 a View similar to Fig. 1, with theshutter elevated and shown in section; Fig. 6 a view similar to Fig. 2,with the shutter elevated; Fig. 7 a plan view showing the cover wideopen to disclose the interior construction; Fig. 8 a bottom plan view ofthe day-selector disk; Fig. 9 a view similar to Fig. 2 with parts of theshutter broken away; Fig. 10 a sectional side elevation of the device asshown in Fig. 6, the sectional view corresponding to the line 10-10 ofFig. 7; Fig. 11 an enlarged sectional detail corresponding to the line1111 of Fig. 5; and Fig. 12 a view in elevation of the form of key orunlocking device for the shutter.

Describing the various parts by reference characters, 1 denotes acylindrical metal cas ing having a cover 2 provided with hinged lugs 3by means of which it is hinged to the lugs 4t projecting from thecasing, the pivot pin being indicated at 5." The cover is preferablyprovided with a rim 2* adapted to overhang the top of the casing.

The casing is preferably formed as acasting and has opposite the hingelugs a fin or projection 6, with a pair of vertical ribs 7 and 7extending downwardly on each side of such projection, the rib 7 3 havinga recess 7 extending thereacross and the rib 7 have ing a similar recess7 which does not extend entirely across the latter rib but which ter-'minates within the outer edge or surface thereof. a seat for the key bywhich the shutter is unlocked.

The cover is provided with a series of apertures 8 extending generallyradially thereof. Seven such apertures are shown, one for each day ofthe week, each aperture being adapted to register with one of the sevenannular day spaces shown on the record-receiving element (shown. as arecording disk 9) cooperating therewith and to which further referencewill be made hereinafter. The apertures are preferably formed in athickened or ribbed portion of thecover, indicated at 8 Projectingupwardly from the cover is a lug 10 to which a chain 11 is. connected,the said chain having secured thereto a punching tool 12 having apointed end 12 adapted to puncture, or make a suit able depression in,the record disk 9, the latter being preferably of paper, with the partbeneath said apertures 8 supported by an anvil 14 which is secured tothe, inside-of The recesses 7 and 7 constitute the casing by a flange 11 and which is provided with apertures 14 registering with the apertures8 and allowing the point 12 of the tool to prick the diskfsee-Figs. 7and 11). The tool 12 is provided with a head 12 which receives andsecures in place the upper end of a helical spring 13, which springnormally holds the pin 12 in elevated position with its point away fromthe disk 9, whereby the point of the tool is prevented from sticking inthe aperture made in such 'recorddisk andthus tearing'the latter.

adapted. to receive therewithin, when the shutter is lowered,,the rib 8with its apertures-8, and the tool 12 and its anchoring lug 10 and chain11; also the upper end ofthearm or projection for the day-selector disk.At its front or swinging end; the

' shutter is provided with an integral flap or extension 18?, which 1sadapted to extend scr pss' and cover. the front edges of the ribs thisfiapis a flat spring detent 19 the upper end of which is bent inwardlyor rearwardly and is of such length as to catch beneath the locking lug16. The front face of the locking lug is beveled downwardly and forwardly, as indicated at 16 This beveled surface cooperates withtherearwardly die rected end 1.9 of the spring-plate detent to force thelatter outwardly and forwardly as the shutter is swung. to. its loweredposition. As soon as the upperend of the detent clears the lower end of.the inclined face 16', it snaps beneath the lug andholds the shutter inlocked position V For the purpose of unlocking the shutter the tool or.key shown in Fig; 12 is provided.

This tool or key, indicated generally at 20, has a cylindrical end 20which is adaptedto be seated in the recesses 7 and 7", with the lugs 20presented inwardly or rearwardly,

the recess T being provided with an exteir sion 7 through which the lugsmay be in:

serted into the space'or recess between. the ribs. By rotating the key,the lugs 2O will strike the detent springv and disengage it from beneaththe locking lug 16, whereupon the; shutter may be swung upwardly aboutits pivotN thus permitting access to all of theparts covered thereby.

"Reference'has beenrnade to the record Secured to the inner or rear faceof sheet or disk 9. This sheet or disk is pro vided with radial linesdefining hour spaces, twelve such spaces being shown. In addition, it isprovided with seven concentric annular spaces, corresponding to the daysof the week. Each record disk is supported on top. of a platform 21carried by the final shaft of a clock-mechanism (not shown) such as isusually employed with recording clocks of the type to which thisinvention relates. aThe record sheet or disk is conveniently applied andsecured in place by having a central aperture therein adapted to receivea central post or extension 21 of the final drive shaft, which centralpost maybe supported by the platform on which the centralpart of therecord disk is mounted. The disk is conveniently secured in place bymeans of pins 21 projecting upwardly from the-platform and a cooperatingdisk 22 having a central hub cap 22 by means of which it may he slippedover the post 21, the disk being provided with slots to permit'thepassage of the pins through the record disk. This construction affords asimple, efficient, and economical manner for detachably securing therecord disk in place.

As pointedout hereinbefore, the disk is arrangedeso that it will berotated across the anvil l4, enabling the tool 12 to punch upon theproper day segment of the disk the hour of the day at which the recordis made.

The cover is also provided with a locking post 23, which is adapted toenter a vertical slot 24'formed between a pair of projections 25 and 26extending inwardly from the inner face of the casing, one of saidprojections being. shown as provided with a slot 27, which may receive astriker adaptedto perforate the dial record sheet whenever the cover isunlocked, as shown, described and claimed in my patent hereinbeforereferred to. As is the case with the construction disclosed in saidpatent, the lug 23 is provided with a perforationfor the locking 7bolt28,which locking bolt is adapted to be operated by a key inserted ina short barrel 29 projecting outwardly from the casing and located. inthe recess between the ribs 7 andT This barrel and recess are are rangedto be covered by the depending 8X1 tensionplate of the shutter, so-thatthe cover cannot be unlocked and opened without openingthe shutter; and,in the event that it is so opened, the striker will pierce the recordsheet and thus show the fact and the timeof the opening of the casing(as set forth in myearlier patent.)-

Journaled upon-a stud 30 depending from the centralportionof the innerface of the ranged in a curve, so that, by partial succes-l sive rotarysteps of the disk, the apertures 31* may be brought successively intoregister with the apertures 8, beginning with the central or innermostaperture of each series. The disk is provided with notches 32, 32, 32*,32, 32, 32", 32 32 adapted to be engaged by a spring detent pawl 33. Thenotch 32 is adapted to be received by the end of the detent pawl at thetime when the innermost aperture 31 is in register with thecorresponding aperture in the cover, at which time the feeding pawl 34'will be in engagement with the notch 32.

The feedin pawl 34 is carried by a radial arm 35 pivoted on the stud bymeans of a central hub or enlargement and a washer 36. The arm 35 isthickened at one side and provided with a radial series of apertures 35,which register with the apertures 8 in the cover and with which theapertures 31 are adapted to register. The arm 35 is also provided withan arcuate extension 35 to which a spring 37 is secured, the oppositeend of the spring being secured to a lug 37' on the cover. The operatingarm or projection 38 for the arm 35 (to which reference has been madehereinbefore) projects through the arcuate slot 15 in the cover and isadapted to be covered by the shutter 18, when the latter is lowered.

With the parts arranged as described, it is believed that the operationwill be readily understood. Assuming that the platform and post 21 aredriven by the usual clockmechanism so that the recordin disk 9 will makeits revolution in the desire interval of time (say 12 hours),'thewatchman or patrolman, arriving at the station Where this recordingdevice is located, will first insert the key 20 in the recesses 7 and 7and, by'

rotating the same in the appropriate direction will disengage the end 19of the detent spring 19 from the locking lug 16; this will enable thewatchman to swing the shutter upward to the position shown in Figs. 3and 6. He can then punch or indent the record for the appropriate timeof the day and day of the week by inserting the point of the punch ortool 12 into the appropriate'apen ture S in the cover and pressingdownwardly on the head. When the pressure is released, after thepunching operation, the spring 13 holds the point out of contact withthe disk and in readiness for the neXt operation on that particular day,the tool or punch being retained in such inserted position by theshutter.

If it is necessary to advance the day-selector disk 31, the operator cando so by grasping the arm or projection 38 and moving theratchet-carrying arm 35 in the appropriate direction. The length of theslot 15 is such as to enable the disk to be moved one step, and thespring detent 33 will enter the appropriate notch and retain the disk inthis adjusted position. Th watchman or patrolman can then perforate orindent the record disk only by inserting the tool into the appropriateregistering apertures 8, 31 and 35, corresponding to the proper day ofthe week.

Should it be necessary to obtain access to the interior of the casing,this may be done by unlocking the shutter and inserting the key into thebarrel 29, thereby disengaging the bolt 28 from th post 23. Where astriker is provided, such as shown in my patent hereinbefore retererdto, the fact and the time or" so opening the casing will be shown by theperforation of the record disk in line with the slot 27.

hen the day-selector disk shall have been advanced to bring the feedingpawl 3% into the last notch 32% no further movement of the disk by thesaid pawl will be possible, the outermost aperture 31 in the disk atthis time registering with the outermost apertures S and 35. To resetthe selector-disk, the operator can turn the same by hand un til thedetent pawl 33 snaps into the recess 32, at which time the innermostapertures 8, 35 and 31 will be in register. At this time, the recorddisk can be removed and a new one inserted and clamped in an appropriateposition upon the platform 1 The recording device described andillustrated herein is simple in construction and cheap ot production,but accomplishes in a very ,eilicie'nt manner the objects for which itis designed and intended.
